I agree with Mike. The responses that Petaluma's friend got were both CYA statements - neither of which addressed the actual issue at hand, which is that nitro pills are medicine, not explosive and are therefore allowed, always.

Chollie's experience sickens me, for multiple reasons:

1) He had vital life-saving medication confiscated, putting his life in jeopardy.
2) The meds were confiscated because a TSO thought they were "explosives", which is a blatantly untrue urban myth.
3) Every level of supervision above the TSO backed up the TSO. Not one was smart enough to know that nitro pills are NOT explosive. At all. Ever. And are therefore not prohibited in any way, shape, or form from an aircraft cabin.
4) Neither the TSA web site, the TSA blog, nor our newest FT member, TSAPressSec, has ever said simply, "Nitro pills are allowed." They hem and haw and discuss tangential issues, but none of them have the spherical girth to come right out and say that nitro pills are not prohibited, because they're not explosive.
5) Chollie now voluntarily travels without nitro pills, thus endangering his life, because he doesn't want to go through the stress of having his pills potentially found and confiscated again.
